JOHN R. HAMILTON, OF YONKERS,'NEW YORK, ASSIGNOR TO VENTURA ALARM COM-PANY, OF DOVER, NEW JERSEY, A CORPORATION OF NEW JERSEY.

CUTTER FOR PIPE AND THE LIKE.

To all whom it may concern:

Be it known that I, JOHN R. HAMILTON, a citizen of the United States,and resident of Yonkers, in the county of WVestchester, State of NewYork, have made a certain new and useful Invention Relating to Cuttersfor Pipe and the Like, of which the fol lowing is a specification, takenin connection with the accompanying drawings, which form part of thesame.

This invention relates to cutters for pipe and the like, and relatesespecially to cutting apparatus by which pipes, rods, or other materialmay be quickly cut into different sized lengths by providing a series ofspaced stops, any one of which may be operated by a controller and movedinto the path of the pipe to act as a distance piece therefor. Asuitable adjuster and connected adjusting devices make possible a finerelative adjustment between the set of stops and the cutter, either oneof which may be movably mounted, this fine adjustment covering thedistance between two adjacent stops so that the apparatus may be quicklyand accurately set for any length desired.

In the accompanying drawlngs showing in a somewhat diagrammatic way anillustrative embodiment of the invention, Figure 1 is a verticallongitudinal section of part of the device. Fig. 2 is a correspondingtransverse section. Fig. 3 is a top view showing substantially the sameparts. Fig. 4 is a diagrammatic top view on a smaller scale showingsubstantially the whole apparatus; and Fig. 5 is a diagrammaticlongitudinal section thereof.

In the illustrative embodiment of this invention shown in the drawings,the stops may be mounted on suitable rods, such as 25, 28 extendinglongitudinally of the machine and supported in any desired way. Theguide blocks 51 may be mounted between these two rods to rigidly holdthem in proper position and the lugs 26 on the collars 56 on one ofthese rods may be securely fastened thereto at the proper inter-- valsso as to cooperate with the movable stops 55. These stops may be movablymounted in any desired way as by securing them to the stop yokes 29operating between the pairs of collars 69 secured to the rod 28 and anydesired means may be used for Specification of Letters Patent.

moving the desired stop into operative position. For example, the camshaft 27 may be mounted in suitable blocks adjacent the rod 28 and carrythe series of angularly spaced stop cams 20, each engaging the stop roll21 on the corresponding stop. As this cam shaft is rotated one after theother of the stops is raised from the inoperative position shown in Fig.2 to such an extent as to be brought in front of thecorresponding lug 26and into the path of the pipe, rod or other article 24, which asindicated may rest on the blocks 51.

A suitable controller may be provided to actuate the stops as desired,and this controller may be in the form of the controller arm 54 to whichthe control gear 34 is socured and rotatably mounted in a suitable Ibearing, such as 35, see Fig. 3. The control pinion 33 cooperates withthis gear 34 and is secured to the tube 30 formed with the slot 31 inwhich the pin 32 on the cam shaft 27 operates, so that the cam shaft isrotated by the controller. The locking knob 42 may be provided at theend of the controller arm and be connected with a suitable locking pin58 engaging the locking holes 45 in the controller arm 44 so as torigidly hold the controller arm and connected stop devices in positionand maintain the proper stop in operative position in the path of thearticle so that the desired length will be severed by the cutter of anydesired form such as the rotary cutter 5.

In this instance, the cutter is not mounted for longitudinal movementand the relative longitudinal movement between the cutter and stops isprovided by mounting the stops so that they are bodily movable withrespect to the cutter. For this purpose, the wheels 19 are provided onthe blocks 51 so as to coiiperate with the track 17 and enable theseries of blocks, stops and connecting rods which form a carriage to beaccurately adjusted as desired. The adjuster may be in the form of theadjusting lever 47 pivoted about the pin 46, see Figs. 1 and 2, andprovided with the adjuster handle 40 at its upper end with which ifdesired a suitable latch 54 may be arranged to cooperate with thenotches 38 in the latch plate 37, this latch being mounted on the latchhandle 53 pivoted about the pin 41 to accurately indicate theadjustment. effected. A suitable adjusting rod 49 may be pivoted by thepin 48 to the adjuster lever and by the pin 50 to one of the blocks 51so as to bodily shift the carriage and its blocks and stops with respectto the cutter to the extent desired, the amount of this adjustment beingof course sufficient to cover the interval between two adjacent stops,so that by operating the desired stop and effecting the intermediateadjustment by the adjuster any desired length can be secured.

The rotary cutter 5 may be mounted in suitable journals 59 and operatedby the cutter gear 23 engaged by the diagrammatically indicated gearchain 4 operated by the drive gear 64 on the drive shaft 3, this driveshaftbeing operated in any desired way as by the pulley 1 and belt 2thereon, see Figs. 2 and 8. The arms 11, 22 may be swingingly mounted onthe drive shaft 3 in the frame 6 so as to oscillatingly support thecutter and these arms may be operated by the actuating wheel 16 mountedon the shaft 14 having suitable bearings, such as 15, in the frame andcarrying the actuating gear 13 cooperating with the rack 12 on theactuating bar 8. This actuating bar 8 may be pivoted by the pin 10 tothe cutter arm 11 which may be normally held in its upper inoperativeposition by the spring 9 abovethe guide 7 through which the actuatingbar operates. By this means the continuously rotating cutter may bedrawn down by the actuating wheel and connections into engagement withthe pipe 21 upon the cutting rolls 57 mounted in the bracket 18 so as tosever the length of pipe which may then be removed and another pipesection brought forward until its end engages the acting stop 55 at theproper distance from the cutter, as shown in Figs. 3 and 5. Any desirednumber of pieces of pipe or the like may thus be severed and then theapparatus set for any other length desired by the ad juster andcontrolling devices indicated.
